The new DX9 transmitter

Aug 26th, 2013, 04:49 PM

Has anyone seen or tried out the new Spektrum DX9 transmitter? I have a DX8 and love it, but never would have believed that I could run out of a 30 model memory so quickly! The DX9 is claiming a 250 model memory. If nothing else is changed over the DX8, the model memory would sell me, but I know there are also other new features, and only about 50.00 more than what I paid for the DX8 a year ago! Seems like it is almost too good to be true. Any thoughts or comments?

I just checked out the DX9. Interesting. Do Spektrum receivers have built-in battery telemetry? I've been waiting on the Hitec Aurora 9X for over 6 months now. One of the key features I like about that transmitter is I can use Optima receivers in all my models and have battery voltage telemetry without additional hardware. I am currently just shy of 40 planes and would like to equip each with a telemetry capable receiver like the Optima series. If Spektrum has a receiver line with this feature it might end my transmitter wait. I really like the DX9's voice feature and the 250 model memory. Not sure how it stacks up against the Aurora 9X otherwise?

Sorry, I don't know anything about the Hitec Aurora or Optima receivers. I am fairly new to the hobby, only flying for just under 2 years now, and have only used the Spektrum and Tactic radios and transmitters. Both are excellent and I have had no issues with either brand. I have never used a telemetry feature, though I can see how that would be worthwhile! Good luck with your search, I think you could probably find your answer by going to the Horizon website and posting a question there regarding the DX9 and any telemetry functions.

The only part of the telemetry function I am interested in is the live battery voltage feed. Instead of relying on a timer to know when its time to land, you can actually see what's left "in the tank" in real time. This would be especially handy with models like the Fox, V-Tail, and Calypso powered gliders where you are doing a lot of sailing. For most systems, it appears you need a separate telemetry module. With the Hitec Optima transmitters, the battery telemetry is built-in. Hence my draw towards the Aurora 9X. Plus the 9X has built-in SLT compatibility and I have a couple Flyzone models that came with SLT receivers. I could sacrifice the SLT compatibility, but I would really like a system where the receivers have built-in battery telemetry. Buying 40+ telemetry modules would be cost-prohibitive.

I saw you mentioned the Calypso glider. I have been interested in trying a powered glider and the Calypso is one I like. Have you been pleased with it, and does it fly well for a first glider? I have several Flyzone planes as well, one of my favorites is the Cessna Corvalis. Thanks for any suggestions!

I received the Calypso early this week and have not assembled her yet. She arrived in perfect condition, and the foam has a very nice finish. I love the green & black color scheme. Especially nice is the color is on both top & bottom so keeping visual tabs on her at altitude will be easy. Assembly should be very fast...one screw for the tail feathers, one for each wing. Main wing linkages are already connected, and the tail horns are already installed. I ordered the RX-R model so just install the receiver and adjust the linkages and she is ready for flight. I ordered the flap kit for mine so a few more minutes to install the flap components.

I have three powered gliders...the FMS Fox, RocHobby V-Tail, and now the Flyzone Calypso. All three are still in the box. The other Flyzone model I have is the DHC-2 "Beaver." Alas, the Beaver is still in the box also, but the components are beautiful.

I use a separate telemetry unit for my DX8. It has many functions that I think you might like. The unit is easily removed to use on different planes. Moreover, there has been a price decrease since I purchased my units. The DX 9 has built in telemetry.
